On Monday, the Board of Professional Responsibility accepted Weirich’s request for a private reprimand.

The District Attorney said she’s relieved to put the incident behind her but Jackson doesn’t think the punishment goes far enough.

There’s no love lost between Weirich and Jackson.

“The complaint was filed by a friend of the convicted murderer, Noura Jackson,” said D.A. Weirich.

Jackson is a convicted murderer, accused of stabbing her mother to death.

She is also a free woman, because her conviction was thrown out after the Tennessee Supreme Court found Weirich and co-counsel Steve Jones made improper comments during Jackson's trial, and they did not turn over key evidence to the defense.

It’s been the center of disciplinary hearing for the city’s top prosecutor who was on the defense.

“The boards decision was to move forward with the hearing, costing Steve Jones and myself a tremendous expense, both financially and personally," said Weirich.

The long and public battle ended Monday.

“Today the Board of Professional Responsibility informed us that they will not be appealing the ruling on Steve Jones matter and they are dropping all charges against me as well, and have agreed to the private reprimand that we asked for in December 2015. Ending this matter completely.”

Noura Jackson was released in 2015 after pleading guilty to a lesser charge of voluntary manslaughter. When she heard the news of the private reprimand, she sent a statement to FOX13.

“It is surreal beyond belief to see this end with the "no deals" prosecutor accepting a plea and admitting that mistakes were made in the prosecution of this case. If Ms. Weirich is sincere and remorseful, she will have the opportunity to assist the Innocence Project as they request a review of the DNA evidence that points to an unknown suspect," wrote Jacksonz

Jackson has always maintained her innocence.

Weirich has always maintained that, despite an error, her intentions were for justice.

“It is been a long and hard year for my family. Today is a validation that no matter the sacrifice it is imperative every day and always to do the right thing for the right reasons,” said Weirich.

Weirich said validation. Jackson said injustice.

Weirich's assistant district attorney, Steve Jones, was cleared of any wrongdoing by the board in early March.
